SANITARY DRY CLOSET.

nostrano.

To @ZZ 'whom t may concern Be it known that we, GUY PoSsoN and LULU PossoN, citizens of the United States, residing at Los Angeles, in the county of Los Angeles, State of California, have invented new and useful Improvements in Sanitary Dry Closets, of which the following is a specification.

This invention relates to a closet of the type generally known as dry closet (or any other receptacle for olfal, such as garbage and the like) in that it does not require the provision of running water for flushing and cleansing; and the prime object of the invention is the provision of such a device that all closet matters are entirely sealed and disinfected and all odors absolutely prevented from emanating from the closet.

Broadly considered, our invention consists in the provision of a suitable liquid receptacle in which is placed a certain quantity of water covered by a film of disinfecting oil. This disinfectant we prepare especially for this use, the one most preferred having an oily nature and being capable of fioating on the surface of the water. Means are provided for forcing below the surface of the p water and below the film of oil all closet matter; and the oil lm then forms a thorough seal against any odors or gases arising through the water and bubbling out to the air. Moreover, the matter is coated entirely with a film of oil when it is forced through the upper water surface, thereby more thoroughly disinfecting it. This means for sinking the matter below the oil film and the upper surface of the water is actuated through the medium of convenient connect ing levers from the movement of the seat cover provided on the upper part of the device.

Means are also provided for automatically feeding a measured quantity of disinfecting oil to the receptacle each time the seat cover is raised and lowered. This provides for an adequate supply of the disinfectant at all times.

In the accompanying drawings we have illustrated a preferred form of our invention, in which drawings:

Figure 1 is a vertical longitudinal section of our improved device, taken as indicated by line 1-1 on Fig. 2. Fig. 2 is a vertical cross section taken on line 2-2 of Fig. 1.

Specification of Letters Patent.

Application filed August 12, 1911.

Patented Jan. 14,1913.

Serial No. 643,724.

Fig. 3 is an enlarged sectional view showing the arrangement of the oil feed valves. Fig. 4 is an enlarged section taken on line 4-4 of Fig. 1.

In the drawings 5 designates a suitable inclosure having an opening 6 in its upper part and having a hinged seat cover 7. The rear upper portion of the inclosure is formed into an extension 8 which houses an oil tank 9. In the forward lower part of the inclosure is situated a receptacle 10 to receive water 11 and an upper Elm of oil 12. The water is supplied to the receptacle at intervals whenever the receptacle is empty, while the oil is supplied each time the seat cover is raised and lowered. Within the receptacle we have shown a perforated member 13, preferably formed of wire screen, supported by two fioats 14 of such capacity relative to t-he weight of the screen and float-s that the screen will float immediately beneath the oil film 12 so as to force any solid matter beneath the oil film and beneath the surface of the water 11. Floats 14 are connected through the medium of studs 15 to chains 16, one on each side. These chains 16 pass upwardly near the ends of receptacle 10 and pass into curved guides 17, one at each side of the device. Guides 17 first curve upwardly and rearwardly and then downwardly and rearwardly so that, when chains 16 are moved back along the guides, studs 15 are carried first upwardly to the guides, then along the guides rearwardly and thus away from the top of receptacle .10. The other ends of chains 16 are secured to studs 18 mounted in the upper ends of levers 19 pivoted on shaft 25 mounted on the inclosure 5. Portions 19- of levers 19 extend horizontally and at right angles to the main portions of the levers, and the ends of portions 19a are connected by connecting rod 20 to seat cover 7, to which they are pivotally attached at 21. Guides 17 are arranged circumferentially about shaft 25, so that, when levers 19 are revolved, the studs 18 will follow the guides.

When seat cover 7 is' raised it will be seen that the levers will be revolved rearwardly and downwardly and will pull chains 16 and floats 14 along through the guides. The floats will thus first be moved upwardly to the lower ends of the guides and will then be moved rearwardly away from the upper end of the receptacle, leaving the receptacle entirely open, lvllhen the seat cover 'l is again lowered, the chains will be pushed back4 through the guides (the chains fitting; snugly in the guides as shown in Fig. il, and thus capable ot becoming in eil'cct compression members) and the peritorate menr ber 155 vvill be moved bach into the receptacle and doivn to its original position. c object ot the above described movement to open the receptacle; and the above described means are typical. of other meal possible ot employment. The float not arily moved in the particuhir manner described, but We have adopted the movement as an eilicient one. b t fe stated, the vfloats are sutlicientl Y,nt to hold the peritorate meml in about the nos'l on illustrated; so that, as the level. olf the liquid in the receptacle r s, the 'perlorate member will iioat the same distance beloiv the liquid surface, chaine 1G being loose. all solid matter placed in the liquid thus forced beloiv its surface and forced through the lilm of oil, being1 thereby coated ivith the oil disinfectant.

ll/Yhen seat cover i" is raised and lowered., a measured amount et disintocting oil is al Ways supplied to the receptacle. lhis is ettected through the medium ot a pipe 30 leading from the oil tank to a point above the edge ot the receptacle and provided with tivo valves 3l and 'illhese valves have arms 3B Which are connected by a rod let, and both arms are actuated through the medium of a lever 35 which is pivoted at- 36 and is connected by a rod 3?" with rod 20. The arrangement ot the valves is such that When one of the valves is open the other is closed. rthis is clearly shown in ltig. 3. llflien the seat cover i is raised and the lever is oscillated, the valve arms are also oscillated and the valves both turned, one to open and the other to close. rElms, on each raising and lowering oit seat cover 7, an amount ot oil which is contained Within the pipe 30 between the tivo valves is emptied into the receptacle.

Oil tank 9 is also provided with an air inlet valve ll() which is operated through the medium ol a lever iil pivoted at elfi and conf nected by rod d?) to rod Q0. rlhe arrangement is suoli that, when the valves are opened to allonT oil to flow out o'l:l the oil tank, the air inlet valve is opened to allovv air to ilov,T in. This provides that air shall only have access to the disiiii'ecting tank during the short interval ivlien oil is being,` Withdrawn, thus peserving the oil from contamination and om evaporation.
